Form-Focused Instruction (FFI) has been extensively studied, yet past experimental results are often inconsistent or even contradictory. Overly simplistic examinations of grammatical complexity and learner characteristics (e.g., L2 English proficiency) may have fueled the confusion, limiting understanding of how different FFI techniques can be…

Interactions with classroom friends may be an important contributor to first and second language development, but to date this hypothesis has not been tested. Using a longitudinal design, the current study investigated the relationship between classroom friendships and oral language development in children. In 8 classrooms, we assessed the…

Given the significant role vocabulary plays in second language acquisition, how to help learners acquire vocabulary has always been a concern for educators. Despite the general consensus that beliefs influence learners' behaviour, limited research effort has been devoted to the exploration of English as a second language (ESL) learners' beliefs…

Recent studies on the use of Intelligent Personal Assistant (IPA) for second language (L2) learning have found that IPAs such as "Amazon's Alexa" is useful and motivating for L2 learners and that learners' language proficiency might influence their perceptions toward IPAs. However, most existing studies focused on the potentials of…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

The current study investigated how perfectionism can be related to L2 learners' achievement with motivation and two aspects of self-regulated learning as possible mediators. This study also evaluated the factor structure of the Big Three Perfectionism Scale (BTPS) in an Iranian sample. The participants were 495 Iranian high school students who…

Usage-based approaches to additional-language acquisition have identified numerous determinants of language learning, two of which were the focus of our study: frequency and cue contingency. Specifically, we examined how an immersion experience may impact sensitivity to these two determinants as reflected in the production of 4,808 pairs of nouns…

This study focuses on the predictive power of linguistic (i.e., general English proficiency; identified simply as "proficiency" in this paper) and non-linguistic (i.e., language learning anxiety and self-regulation) factors on the academic success of English medium instruction (EMI) students studying in engineering and social sciences…

The Hanyu Shuiping Kaoshi (HSK) is a multi-level, multi-purpose Chinese proficiency test developed by the Center for Language Education and Cooperation (previously the Office of Chinese Language Council International and, henceforth, referred to by its colloquial name "Hanban"). It assesses reading, writing, and listening skills of…

This article explores the interplay between English language proficiency and social class. First, it discusses flaws in cognitive approaches to English language learning and applied linguistics. It then calls for the cultivation of a more holistic approach to learners' motivation and language achievement as the product of both micro and macro…

Though Mandarin Chinese dual language immersion (DLI) has been growing rapidly in the U.S., research on this population is still rare. This study explored cross-language transfer of expressive oral vocabulary knowledge and definition skills among students in a Chinese DLI program. We found significant within and cross-language relationships of…

This study uses a cognitive diagnosis model (CDM) approach to investigate the associations among specific L2 reading subskills. Participants include 1,203 Year-4 English major college students randomly selected from the nationwide test takers of Band 8 of Test for English Majors (TEM8), a large-scale English proficiency test for senior English…

The present study aimed to investigate the effectiveness of teaching intervention for Chinese learners, who were English speakers who tended to focus on phonemic awareness, in learning Chinese. It also tried to examine the impacts of Chinese phonological and morphological awareness on their English language development. The study was conducted in…

This study examined how Korean EFL learners in different proficiency levels attest contrasts of L2 phonology. To this end, twenty Korean EFL learners in high and low levels of English proficiency produced words with word-final contrasts of /[esh]/ vs. /[esh]i/, /t[esh]/ vs. /t[esh]i/, and /d[ezh]/ vs. /d[ezh]i/. Acoustic analyses of lexical vs.…

This dissertation examines the linguistic and cultural difficulties faced by Non-Native English-speaking (NNES) peace officers in the United States, emphasizing English training and job preparedness. The research adopts an explanatory sequential mixed-method design, including quantitative and qualitative data collection and analysis. This study…
